Code P0532 Dodge Description

The P0532 diagnostic trouble code for Dodge vehicles indicates that the A/C refrigerant pressure sensor circuit is detecting a low input signal. This sensor is responsible for monitoring the pressure of the refrigerant in the air conditioning system. When the sensor detects that the pressure is too low, it sends a signal to the engine control module (ECM) to adjust the A/C system to maintain proper pressure levels.

  • So i have a 2007 dodge ram 3500 diesel 6.7 chipped and deleted and I just recently got this code showing up (po532) after having my transmission replaced I'm sure that had nothing to do with why I have this code but the guy did say he messed with some fuses or something like that. I did replace the pressure sensor but a/c still seems to blow very warm due to the clutch not engaging. Not sure what to do from here please help.

  • Have you checked if there is refrigerant in the system? low refrigerant can trigger this code, in fact, is the most common problem.
